I currently have a supermirco setup and I want to upgrade the motherboard but this requires a bigger power supply. I have the 5013C-M case. Can I purchase a supermicro PSU rated for 350W-400W (1U design non hot plug design) that would fit in this case?
Yes, the PWS-351-1H power supply 350W for 512C-260 will fit your 5013C-M case.
